12 At that time King Merodach-baladan son of Baladan of Babylon sent envoys with letters and a present to Hezekiah, for he had heard that Hezekiah had been sick. 13 Hezekiah welcomed them; he showed them all his treasure house, the silver, the gold, the spices, the precious oil, his armory, all that was found in his storehouses; there was nothing in his house or in all his realm that Hezekiah did not show them. 14 Then the prophet Isaiah came to King Hezekiah, and said to him, "What did these men say? From where did they come to you?" Hezekiah answered, "They have come from a far country, from Babylon." 15 He said, "What have they seen in your house?" Hezekiah answered, "They have seen all that is in my house; there is nothing in my storehouses that I did not show them." 16 Then Isaiah said to Hezekiah, "Hear the word of the Lord: 17 Days are coming when all that is in your house, and that which your ancestors have stored up until this day, shall be carried to Babylon; nothing shall be left, says the Lord. 18 Some of your own sons who are born to you shall be taken away; they shall be eunuchs in the palace of the king of Babylon." 19 Then Hezekiah said to Isaiah, "The word of the Lord that you have spoken is good." For he thought, "Why not, if there will be peace and security in my days?"
20 The rest of the deeds of Hezekiah, all his power, how he made the pool and the conduit and brought water into the city, are they not written in the Book of the Annals of the Kings of Judah? 21 Hezekiah slept with his ancestors; and his son Manasseh succeeded him.

Commentary on 2 Kings 20:12-21
(Read 2 Kings 20:12-21)
The king of Babylon was at this time independent of the king of Assyria, though shortly after subdued by him. Hezekiah showed his treasures and armour, and other proofs of his wealth and power. This was the effect of pride and ostentation, and departing from simple reliance on God. He also seems to have missed the opportunity of speaking to the Chaldeans, about Him who had wrought the miracles which excited their attention, and of pointing out to them the absurdity and evil of idolatry. What is more common than to show our friends our houses and possessions? But if we do this in the pride of ours hearts, to gain applause from men, not giving praise to God, it becomes sin in us, as it did in Hezekiah. We may expect vexation from every object with which we are unduly pleased. Isaiah, who had often been Hezekiah's comforter, is now is reprover. The blessed Spirit is both, John 16:7,8. Ministers must be both, as there is occasion. Hezekiah allowed the justice of the sentence, and God's goodness in the respite. Yet the prospect respecting his family and nation must have given him many painful feelings. Hezekiah was indeed humbled for the pride of his heart. And blessed are the dead who die in the Lord; for they rest from their labours, and their works do follow them.
